| Research Abstract |
Recently, zinc-releasing bioceramics have been the focus of much attention owing to their bone-forming ability. Thus, some types of zinc-containing calcium phosphate (e.g., zinc-doped tricalcium phosphate and zinc-substituted hydroxyapatite) are examined and their osteoblastic cell responses determined. In this investigation, we studied the effects of zinc calcium phosphate(ZCP) derived from zinc phosphate incorporated into calcium phosphate cement (CPC) in terms of its setting reaction and MC3T3-E1 osteoblast-like cell responses. The proliferation of the cells and alkaline phosphatase (ALP) activity were enhanced when 10 wt% ZCP was added to CPC. Taken together, ZCP added CPC at an appropriate fraction has a potentpromotive effect on bone substitute biomaterials.
